What Neotiss does

Neotiss SAS is a French-headquartered manufacturer specializing in thin welded tubes made from titanium, stainless steel (austenitic, ferritic and duplex), and high-nickel alloys, serving customers in power generation, desalination, petrochemical, chemical, automotive and aerospace markets. Founded in 1976 to support the French nuclear program, the company has grown into a globally recognized producer with manufacturing operations in France (Venarey-Les-Laumes), the United States (Morristown, Tennessee), China (Changzhou) and India (Hyderabad), plus a joint venture in South Korea (Poongsan Neotiss, Pyongtaek). Sales coverage extends to five countries across three continents.

The company's product portfolio is centered on high-performance welded tubes in straight, U-bent, smooth, corrugated, low-finned, helix and inner-ribbed configurations, ranging from 10 cm to 25 m in length. Core proprietary offerings include the patented NEOTISS™ Helix Tube, which delivers more than 40% heat transfer improvement over smooth titanium tubes; NEOTISS™ HPT Finned Tubes, providing 2.5 to 3 times the external surface area of smooth tubes; and NEOTISS™ MSR Tubes, built on an optimized TP439 ferritic stainless steel that has become an industry standard for nuclear Moisture Separator Reheaters. Manufacturing relies on TIG/GTAW and laser welding technologies backed by in-house advanced non-destructive testing, including in-line helium leak testing. The company holds IATF 16949:2016 automotive certification and has delivered more than 500 power plants, 160+ nuclear MSRs, 220+ nuclear condensers, 170+ nuclear feedwater heaters, 90+ desalination plants and 20+ LNG trains.

Neotiss generates revenue primarily through B2B sales of customized, quote-priced welded tubes to large industrial OEMs and engineering firms (including General Electric, BHEL, Larsen & Toubro, Siemens, Doosan, Foster Wheeler, Naval Group and Total), supplemented by e-commerce sales of standard products via Alibaba.com and 1688.com. Pricing is not publicly disclosed and each order is engineered to customer specifications, supporting a hardware-sales model with long qualification cycles, particularly in nuclear and aerospace. The company is privately held under French parent Neotiss SAS, with consolidated revenue of approximately €100 million and 600+ employees globally.
